Abstract (en)
[origin: WO9957220A1] Compounds for organic EL devices exhibiting electroluminescence satisfactory in luminance, particularly a long-wavelength one, and being so excellent in durability that the good luminescence performances can last over a long period; and organic EL devices made by using the same. The compounds have basic skeletons represented by general formula (1): wherein R<1>, R<2>, R<3> and R<4> are each optionally substituted aryl or alkenyl; and R<5>, R<6>, R<7> and R<8> are each hydrogen, with the provisos that two or more of R<1> to R<4> are each aryl which is at least bicyclic or has a substituent selected from among aryl, amino, alkenyl, aryloxy and heterocyclic groups, or alkenyl, that when two or more of the substituents are each monocyclic aryl, they have additional substituents, and that when the substituent is amino, two or more of R<1>, R<2>, R<3> and R<4> are each substituted with optionally substituted aryl.
